Audi plans to begin offering the initial version of Piloted driving - called Traffic Jam Pilot - to the public within five years.

The ability to conduct research in the real-world conditions offered by Florida and the Expressway Authority is crucial to pre-production development, Audi said in a statement.

In 2012, Florida Gov. Rick Scott signed into law a bill that allowed the testing of autonomous vehicles in the state, making Florida one of only three states where autonomous vehicles can be piloted on some designated roads. Tampa's Selmon Expressway, where the Audi A7 was piloted, was recently designated as an autonomous driving technology test bed.

California and Nevada have also passed legislation to allow self-driving vehicle testing on roadways.
